Let's see... AoE. Potentially attackers you need to defend yourself from. Healers.
You seriously need to gimp yourself hard if you want to kill the resurrector, and only it before any other opponents in a lot of cases (I tried with the Pirate, and it healed just back to full with even more hitpoints than original!)

So;
* Effort to exploit, many reloads
* Massively nerf yourself in combat NOT to get it, doesn't require active player partipation to get affected by.

Surely you can tell the difference?
Divinity II also had this mechanism, and while you could reload for 3 malachites on ore, not many people did that.
It's worked for all Divinity games so far, why suddenly change it now?
